原创 EETimes Asia Puzzle: Mystery MOSFET loads

What are the missing loads? This circuit board plugs into something, but we know not what.

From the clues (there are at least four of them) hidden in the schematic above, what would you say are the most likely loads for the drains of transistors Q1 and Q2 connected to EdgeConn1 and EdgeConn2, respectively? Also, please describe what led you to your conclusions.
